Air inlet grille structure for indoor unit of cabinet air-conditioner

Abstract

The invention discloses an air inlet grille structure for an indoor unit of a cabinet air-conditioner, which is detachably fixed at an air inlet of the indoor unit and comprises a guide hood and a grille integrally formed with the guide hood by means of injection molding. A fixing structure which can be used for fixedly connecting the guide hood with a fan housing is arranged on the guide hood. The grille comprises a plurality of round grille strips concentrically arranged on a same plane and radial grille strips in a star form, the radial grille strips sequentially and fixedly connecting the round grille strips, and the tail ends of the radial grille strips are fixedly connected with the guide hood. The guide hood and the grille are integrally formed by means of injection molding, so that mould development is reduced, processing cost is reduced, and mounting cost can be saved. The grille is in a cobweb layout, wind resistance is reduced while strength of the grille is guaranteed. By means of the grille in a plastic structure, cost is reduced while rustiness and the like at the later stage can be effectively avoided, and appearance of products can be guaranteed.

Description

technical field [0001] The invention relates to an air intake grille structure, in particular to an air intake grille structure of a cabinet type air conditioner indoor unit. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, condensation process, expansion process, and evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state can dissipate heat to the outside in the condenser, and when it flows through the expansion valve, its temperature and pressure are significantly reduced, and then the low-temperature, low-pressure refrigerant is in the air. It absorbs heat as it passes through the evaporator and flows back into the compressor. Among them, the compression process, condensation process and expansion process are carried out in ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned existing connection structure between the air inlet and the air intake grill needs to install screws one by one during assembly, resulting in long assembly time, waste of screws, and high cost

In addition, the air-conditioning indoor unit air intake grille 131 is arranged in a criss-cross pattern, which increases the wind resistance and increases the load on the motor of the indoor fan, which affects the overall performance of the machine.
